A1469 Apple TV box no longer "Activated" and won't show up in AirPlay
My dad has been using this Apple TV box for years (says he got it about 7 years ago) and the **only** thing he's ever used it for was AirPlay where he would mostly send YouTube videos to his TV from an iPad. He doesn't care about using it for anything else But recently he saw something that said it needed an upgrade (which he approved) and then at that point it stopped showing up as available on AirPlay. I tried helping him by restoring it to factory conditions, logging in with his Apple ID (where it went through 2FA on his other devices), and seeing it if showed up. The best I can gather is that it's "not activated". Tried changing the credit card number on file and nothing changes with the activation status. Not sure if that's absolutely needed for AirPlay.
I did find something claiming that it might be activated with Apple Configurator on a Mac, but I don't currently have access to a Mac that can run it, where it requires MacOS 12.4 or later.
I helped him to set up his LG TV, which is also rather old but still working fine. It wasn't previously connected to his network, and when I did set that up it started showing up as AirPlay enabled as "[LG] WebOS TV". And it does work sometimes where he can send video from his iPad directly to the TV. That would be more than acceptable for him other than after a while it disappears as one of the available AirPlay enabled devices/TVs but then comes back.
